Travis, well said, eloquently as someone put it. I feel the same way though less strongly after all the years. Particularly the more strenuous part of it but I can say that for yard work too. For example yard bunnies, squirrels and such get a pass so long as they're not causing damage because I like to watch them. But no regrets or sadness if they need to be popped, I enjoy that too.
A little introspection would be interesting, why do you feel that way? Of course not necessary but can lead you to interesting places.
